Each female fly lays on average 100 eggs, which are placed singly on the body of a large nymph or adult bug. Most of the small, white or gray, oval eggs are placed on the underside of the thorax or abdomen, but they can occur on almost any part of the bug. Many eggs may be laid on the same host, but only one larva will survive in each bug. The young larva that hatches from the egg bores directly into the host body. The maggot feeds on the body fluids of the host for about two weeks, during which time it increases to a size almost equal to that of the body cavity of its host. When it has completed its development, the cream-colored third instar maggot emerges from the bug between the posterior abdominal segments. The bug dies after emergence of the fly, not from the parasitoid feeding, but from the mechanical injury to its body. The maggot pupates about an inch down in the soil in a dark reddish-brown puparium formed from the last larval skin, and an adult fly emerges about two weeks later. There can be three generations per year depending on location.
The fly overwinters as a second instar larva within the body of the overwintering host bug. Adult flies emerge in late spring or early summer. The only bugs large enough to parasitize at this time are overwintered adults. Subsequent generations develop on both nymphs and adults of the next generation.

At American Beauties Native Plants, we take a slightly broader view in our definition of native plants–we include cultivars. A cultivar is a plant that has been selected and cultivated because of some unique quality, such as disease resistance, cold hardiness, height, flower form or color. Sometimes interesting varieties are found in nature and brought into cultivation making them cultivated varieties or cultivars. In my years as a research horticulturist I observed pollinators, birds and other wildlife interacting freely with cultivated plants.This paragraph is immediately followed by a photograph of "[Echinacea] ‘Tiki Torch’ is a hybrid of Echinacea paradoxa and a cultivar of Echinacea purpurea."
